/* Sicut — the public face, in the same metal as the tool.

   THE INSTRUMENT, spoken slightly louder: machined graphite, silvered aluminum, engraved
   mono labels, tungsten warmth, and the answering horizon (horizon.css) holding first light
   at the foot of the page. The serif italic is the Latin voice — the wordmark, the tagline,
   and the emphasized phrase in the hero — and appears nowhere else.

   Everything is classes; the CSP is style-src 'self' with no unsafe-inline. Fonts are
   self-hosted (static/fonts, OFL). Token values match app.css exactly so the front door
   and the tool are one object. */
